Cams Infinitum…

If you plan to run solid lifters get the lifters with a laser .012" oiling orifice in the center contact area of the lifter.
Solid lifters can open the valves at a faster rate of lift if designed so by the grinder.
Thus the valves will be open more than a juice lifter. The area under the curve is increased.
One might have to run valve springs with more tension to handle the faster rate of lift.
A solid lifter camshaft will put out more power & can be run at a higher rpm.

Where are you finding the "laser .012" oiling orifice" lifters? I was looking to do some more research and I am having trouble locating them.

KB, comp cams has the lifters with a .012" laser oiling hole for their solid lifters. Bill

Got it, I know what to look for now. They're not list under the engine lookup, if you go to the perfomance lifter section and select Ford, they are under "Performance Series™ Lifters w/ EDM™;"

Specs – .875” diameter; 102g weight; 1.79” seat height (comp cams: stock replacement value)
Specs – .875” diameter, 97g weight; 1.95” seat height and .012” oil hole (comp cams: performance replacement value)

Thank you!

Guys, watch the seat height of these lifters. The yella-terra 1.65 rocker arms are the only ones that use the 302-351W oil through lifters.
If they list one for the FE engine that is the one to use for the non oil through pushrods which are .200" shorter than the Windsor series engines. Bill

Fords engine designers used a lot of modular technology in the Windsor, Cleveland, Lima and overseas Geelong plants, so parts from other engine families swap in with some additional work. That applies not just to the future potential of roller cammed non cross flow small sixes, but also to the existing Classic Inlines and 2V conversions, which seam to have plenty of camshaft technology thrown at them for well over half a century. A solid or hydrualic cam will exceed your expectations. Sometime in the next few years, roller cam conversions will be easy, but presently, they are an Aussie cross flow and Argentinian SP 221 and ME 188 kind of thing. The reason is that the spider, button or tie rod technology won't blend into the non cross flow as easily as it does with the cross flow and Big sixes. Its an area that is very tight. The solution is actually dead simple, (it just needs an extenal template to punch 12 small brass plugs in the side of the block to hold the aftermarket slotted roller cam followers), but like adapting auto over drives and fuel injection, the market hasn't cottoned on to the simplicity of it yet. :mrgreen:

That must be an aussie cross flow block? Our's look a bit different, we don't have that much clearance inside the block on the ourter most lifters. I'll have to take a pic tonight and post it up.

....POINT 1: For the older non cross flows, a spider or brass button is needed for all 12 tappets, as unless you riffle drill a 0.625" hole the span of 21 inch long hole through the block bulkheads to allow the tie rods to work at the lifts you require, that's all that works. The Argie guys do both set ups, but mostly running a bore bar through the block

POINT 2: X-flow blocks are different to the non cross flow in four ways, but they moved the water galleries away to the other side of the engine, but asside from the valve order, the X-flow roller cam fits the non cross flow block, and just needs buttons to secure the groved type of aftermarket roller cam followers.

Summary of Point 1 and Point 2. The non cross flow 1960-1983 US and 1960-1995 Argentine and Aussie 1960 to 1976 engines all had the water galleries on the side of the camshaft. The X-flow had the water gallery swapped to the other side, so the non cross flow has less bulkheads and the tie rods fit with just a little die grinder work. The non cross flow has six of the 12 lifters surrounded by a cast iron water gallery. A 0.625" hole through each bulkhead would allow the 385 Lima style lifter tie rods to be linked. Jack Collins told us about this heroic method of roller camming a non cross flow by the Argentinians back in 2005...The alternative is 12 brass bottons to hold the special aftermarket bottomlifter retrofit kits, which eliminates the need to riffle drill the block through its six bulkheads over 21 inches, each which holds a water gallery on the non cross flow.

There are three methods.
1.335 Cleveland or 385 Lima style tie bar


2.Spider

3. Button slide (a stock tie rod roller with a brassbutton which slides up and down a runner in the block)

Here are seven shots which show the differences between my black 1983 Aussie cross flow 4.1 and my red 1966 Aussie non cross flow 200 six. See the US head gasket verses the Aussie X-flow composite gasket. I think your getting the picture. There were some photos in the Classic Inlines tech pages from Jack Collins Crossflow Chronicles. Thanks Mike W (AZCOUPE). The head has to have a new profile to fit the canted valve X-flow heads, but the 200 US block has the same hard dimensions for camshaft and lifters as the Aussie X-flow, its just that six water galleries are seperating some of the twelve lifters. And Jack has actually showed how a plate might be added to hold twelve lifter buttons via cap screws on the outer block, were he just added a 20.25" long steel plate to the outer block to support the wider cross flow head. The same thing could be used to create a 12 plug lifter gallery holder for the groved roller rockers.Food for thought...

Dean, what kind of distributor gears are they running?
If its a steel billet camshaft you are forced to use bronze gears.
Here in the USA they don't even offer decent stock gears.
I had to have some gears custom nitrided to 40-45 Rockwell C & then parkerized them.
They hold up even better than the gears from Crow cams.
